Yes, I don't know much about specifiers, but indeed, I'd much rather have
something different than just "variables".

E.g. one of the benefits of "frame-local" variables over using
`frame-parameter' is that the user-code doesn't have to know that the data
is local to frames.  So if we later decide to make it terminal-local or
keyboard-local, or window-local the same code will work fine.

So using a new function (get-local-data SYMBOL) we could take care of such
problems.  I suspect that is indeed what XEmacs's "specifiers" are for.
